Mobile High-Definition Link (MHL) allows a standard USB connector to carry digital video signals. To use the MHL output from a mobile device using a micro-USB connector, the MHL output must be converted by using an MHL adapter. MHL can only be adapted to HDMI.

Although many mobile devices use the micro-USB connector and the MHL adapters can plug into your mobile device, the mobile device still requires MHL support. MHL support is a hardware specification on your mobile device, and it cannot be resolved by applying updates of any type.

To determine if your mobile device supports MHL, research the manufacturer specifications for your mobile device. You can also search for your device on the following website: http://www.mhltech.org/devices.aspx.

To make sure that you select the correct adapter, you need to determine if you are using a 5-pin or 11-pin micro-USB. This information can usually be found with the MHL specification on your mobile device.

Different types of Samsung devices that use an 11-pin micro-USB require external power to perform the conversion. First-generation Samsung MHL 2.0 requires external power, whereas the second generation does not. A passive 11-pin cable can be used with second-generation Samsung mobile devices.

StarTech.com 5-pin and 11-pin adapters have a micro-USB receptacle to provide additional power to the mobile device. You can use a standard micro-USB cable with a USB charger to power the converter.

Troubleshooting

When you troubleshoot issues with an MHL adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

Mobile device

Display

Video cables (if required)

To test your setup components, try the following:

Use the mobile device, display, and video cables in another setup to see if the problem is with the components or the setup.

Use a different mobile device, display, and video cables in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

Test each cable individually.

Use short cables when you are testing.

Note: You should avoid using adapters to further convert the HDMI signal. If you need to further convert the HDMI signal, make sure that all of the adapters and displays are compatible with the output resolution of the mobile device.
